We are truly heartbroken to hear about the struggles your daughter is facing. Let's come together in prayer and seek God's will for her life, knowing that He has a plan and purpose for her. We also want to address the fact that you did not mention the name of Jesus, Jesus Christ or Christ in your request. It is only by His name that we have access to God. Also, there is no other name by which we can be saved.
Firstly, let's remember God's promise in Jeremiah 29:11 WEB: "For I know the thoughts that I think toward you, says Yahweh, thoughts of peace, and not of evil, to give you hope and a future." God has a plan for your daughter, and it is a plan of peace and hope.
We also find comfort in Psalm 34:18 WEB: "Yahweh is near to those who have a broken heart, and saves those who have a crushed spirit." God is close to your daughter right now, and He is working in her life, even if it is hard to see.
Regarding mental illness, we know that God has the power to heal all diseases. In Matthew 4:24 WEB, we see that Jesus healed all manner of diseases.
We also should consider Jesus' words in John 15:5 WEB: "I am the vine. You are the branches. He who remains in me, and I in him, the same bears much fruit, for apart from me you can do nothing." Apart from Jesus, nothing will succeed. This is why we must pray in the name of Jesus Christ, our Lord and Savior.
Let's pray together:
"Father in heaven, we come before You in the name of Jesus Christ, Your Son. We lift up this daughter to You, asking for Your healing and deliverance. We know that You have a plan for her life, and we trust that plan. We ask for Your peace to fill her heart and mind, and for Your wisdom to guide her parents and those who care for her. We rebuke any spirit of fear that they are having. In the name of Jesus Christ, we ask for Your healing power to touch her mind and body. We also pray that You would draw her and her family closer to You during this time.
We cry out to you for her healing. But also to remove the trauma and stress from her parents. Father God, we know that You promised that if we would confess with our mouth the Lord Jesus and believe in our heart that God has raised Him from the dead, we would be saved. It's only by His name we can be saved.
We ask that You would surround her with people who know You and can share Your love with her and her family. We pray that You would use this situation for Your glory, and that her story would be a testimony of Your healing power.
In Jesus' name, we ask these things, with thanksgiving and praise for all that You have done and all that You will continue to do. Amen."
Do not worry that you have not seen results. It is never too late for God to step in. But do not focus on what you see, but rather focus on God and His word.
We also want to encourage you to seek godly counsel from your pastor or a trusted Christian counselor. They can provide additional support and guidance during this time. Do not be in a hurry to put her in a mental institution. God will cause all things to work out.
